Description of the new type: [Technical field to which the new type belongs] This creation relates to a one-way transmission wheel of an automobile generator, particularly a one-way driven wheel installed on the rotor end of the automobile generator and linked to the engine. Car generators can generate electricity with the engine. [Previous technology] It is known that the car generator is driven by the engine, which can generate electricity storage at any time during driving or provide it for use by various parts of the car. Therefore, the pulley and belt are used as the power transmission structure between the engine and the generator. Referring to the sixth figure, a passive pulley 10 is usually connected to the rotor shaft end of the automobile generator, and a multi-slot belt 20 is set between the passive pulley 10 and another active pulley at the engine end to drive the car. Motor function; however, when the car is traveling at high speed, the passive pulley 10 and belt 20 are driven by the engine to run at high speed. When the car brakes rapidly and the engine speed is reduced, the pulley 10 and the belt 20 will pull and the rotor shaft 60 The speed difference between the pulley and the pulley due to inertia, and then returns to the speed of the pulley 10, not only easily = pulling the belt 20 to cause slack, but also causing a loss of locking torque at the joint between the pulley 10 and the rotor shaft 60, or affecting the The motor operates. In this regard, there is a pulley 1 that can prevent reverse rotation. It is proposed that, as shown in the fifth figure, a special one-way bearing 30 is provided in a pulley 10, and the one-way bearing 30 includes a mutually fitted bearing. An outer ring 301 and an inner ring 302, and a one-way needle roller 303 and a two-way needle 304 are provided between the outer ring 301 and the inner ring 302, and a sleeve 40 'is inserted through the inner ring 302. The sleeve 40 provides a connection to the generator rotor shaft 60. Due to the arrangement of the one-way bearing 30, an idling effect can be generated when a speed difference occurs in the pulley 10, so the locking torque can be ensured and the belt life can be increased; The one-way bearing 30 is specially designed and manufactured, which not only has higher use cost, but also results in complicated internal structure. M276709 [New content] The main purpose of this creation is to provide a one-way transmission of automotive generators = wheels. Specialized one-way bearings and ball bearings with belt pulleys as towels, as well as improvement of the assembly structure with the sleeve , Forming a one-way transmission wheel that can absorb the speed difference, and achieve benefits such as simplified structure and reduced cost. According to the above purpose, the implementation content of this creation includes a stepped shaft hole in the center of the pulley, which is generally set in the shaft hole-standardized one-way bearing and two ball bearings. A sleeve is inserted between the two bearings. The sleeve provides automobile generator ^ rotor shaft connection, and a washer ring is provided at the end of the sleeve and rotor shaft connection end, thereby forming a unidirectional transmission that can ensure the locking torque and increase the belt life. The one-way bearing and ball bearing arrangement are simplified, so the structure is simplified and the use cost is reduced. [Embodiment] The following describes the structural features and other functions and purposes of the creation in detail according to the embodiments of the drawings: As shown in the drawing, the creation of "one-way driving wheel of automobile generator" is: The unidirectional driving wheel at the shaft end of the rotor of the automobile generator consists of a leather V wheel 1, a one-way bearing 2, a ball bearing 3, and a sleeve 4, and a washer ring 5 can be provided at one end of the sleeve 4 among which: ^ Pulley 1, as shown in the first to third figures, is a triangular belt pulley with a plurality of V-shaped belt grooves around the wheel ", and a first-stage shaft hole 12 is provided at t, which includes one end An inwardly-shaped convex stop 121 is provided. At the rear end of the stop 121 is provided a unidirectional bearing section with a larger diameter ^ 2, and the rear end of the unidirectional shaft section 122 is adjacent to a larger diameter. Ball bearing section 123, 俾 provides the following one-way bearing 2 and ball bearing 3 installation; ~ One-way bearing 2, as shown in the first and second figures, is a standardized ratio D, ten bearings have an outer The ring 21 is a one-way bearing section 122 installed in the shaft hole 12 of the pulley 1 in a tight fit.

When this creative application is implemented," the rotor shaft connecting part of the sleeve 4 is used to provide the car generator. The rotor is finely screwed. When the leather belt drives the pulley to rotate in the forward direction: the unidirectional bearing 2 is used to synchronously turn the sleeve 4 and the rotor shaft 60. If = the instantaneous speed difference phenomenon, then the idle action of the unidirectional bearing 2 is used. The cylinder 4 and the rotor shaft 60 absorb the difference in speed, so it can protect the rotor shaft 60 and generators and other components. Especially because of the paste, the grid material is combined to the bearing 2 and the sleeve 4 without additional design and manufacture. The previous report shows that the early direction H of the special specification can reduce the cost and simplify the structure of the structure.
